I love Toucans and nearly had one as a pet years ago before I got my parrots. Friend of mine has a private bird sanctuary on the Vaal river where he takes care of birds from all over Africa. He has 2 of each like Noah's Ark being a security blanket for many rare species sent to him via various Park Boards. The noises are unbelievable as it is like Jurassic Park and you can hear his place kilometers away.
Sound they emit make these large beaks quite phenomenal, can imagine the sanctuary sounds in early mornings or late afternoon. I vaguely remember a small zoo on the Vaal river bank, down from Vereeniging station, river rose and they incurred problems and it was closed, a long time ago. Always good to hear of folk that take care of animals, educate those who are not familiar with them.
